Key Takeaways
- Mortgage pricing can vary between lenders, which is why comparing multiple offers can help borrowers understand what rates and costs may be available to them.
- A small rate difference can create significant long-term costs, particularly on larger loan balances or longer loan terms.
- The lowest interest rate isn’t the only factor to consider, because points, lender fees, credits and other closing costs affect the total cost of a mortgage.
- A mortgage offer should be evaluated in the context of the borrower’s specific situation, including loan type, credit profile, down payment, property, closing costs and how long they expect to keep the loan.
A mortgage overpayment can add thousands of dollars to the cost of homeownership, and overpaying a mortgage can happen even when a borrower qualifies for a competitive rate. New research found that 87% of mortgage borrowers in its 2025 analysis paid more than its competitive-market benchmark, with the typical borrower estimated to have paid an additional $3,343 per year. The research highlights why comparing mortgage rates, shopping multiple lenders and understanding mortgage costs can make a meaningful difference when choosing a loan.
What Is Mortgage Overpayment?
Mortgage overpayment doesn’t necessarily mean someone made an extra payment toward their principal. In this context, it refers to paying more for a mortgage than a borrower could have received from a more competitive offer with a similar financial profile.
Research compared 3.2 million 2025 mortgage originations with competitive offers available through its mortgage marketplace. Its methodology accounted for factors such as credit profile, debt-to-income ratio, loan size and loan type when comparing borrowers with similar characteristics.
That distinction matters because two borrowers with similar financial profiles may receive different pricing depending on which lenders they shop and which offer they ultimately accept.
How Much Can Overpaying a Mortgage Cost?
The difference between two mortgage offers may look small at first, but even a fraction of a percentage point can add up over time.
For example, research estimates that reducing the rate on a $400,000 mortgage from 6.50% by 0.25 percentage points could lower the monthly payment by roughly $66 and save more than $23,800 in interest over a 30-year term, assuming the loan remains outstanding for the full term.
This research also estimates that the typical borrower paid about $3,343 more per year than its competitive benchmark in 2025. Over an assumed 30-year period, its modeled figure reaches approximately $78,186. However, the research uses an eight-year cost model for its annual estimate, and actual savings will vary depending on how long a borrower keeps the loan, fees, points and other factors.
The Cost Varies by Location
A recent study found meaningful differences between metropolitan areas.
Among the markets with the widest gaps between borrowers’ selected mortgage rates and Bankrate’s competitive benchmark, the research found:
| Metro Area | Average Rate Spread | Avg. Annual Overpayment | Avg. Annual Overpayment |
| Victoria, TX | 1.24% | $2,841 | $22,729 |
| Tyler, TX | 1.19% | $3,361 | $26,889 |
| Los Angeles, CA | 1.18% | $6,075 | $48,599 |
| Santa Fe, NM | 1.15% | $4,244 | $33,952 |
| Elkhart-Goshen, IN | 1.14% | $2,607 | $20,854 |
| La Crosse-Onalaska, WI-MN | 1.14% | $2,669 | $21,355 |
| Santa Rosa-Petaluma, CA | 1.13% | $5,153 | $41,223 |
| Corvallis, OR | 1.13% | $4,307 | $34,457 |
| Santa Cruz-Watsonville, CA | 1.12% | $5,567 | $44,536 |
| Kiryas Joel-Poughkeepsie-Newburgh, NY | 1.12% | $4,034 | $32,273 |
This study analyzed more than 350 metro areas and defines its market rate spread as the difference between the rate borrowers received and the most competitive offers available through its marketplace.
The important takeaway isn’t that borrowers in one particular city are guaranteed to overpay. Instead, the research illustrates how much mortgage pricing can vary between markets and individual borrowers.
Why Do Borrowers Overpay for Mortgages?
One reason is that many borrowers don’t compare enough lenders before choosing a mortgage.
Research from the Federal Reserve Bank of Philadelphia found that about half of borrowers seriously considered only one lender, while just 3% considered more than three. The researchers also found that mortgage shopping behavior and borrower knowledge were associated with the rates borrowers ultimately received.
The mortgage market is also complicated. Lenders can have different pricing models, fees, loan programs and operating costs, so the first quote a borrower receives isn’t necessarily the only option available.
A recommendation from a real estate agent, friend or family member can be a useful starting point, but it doesn’t have to be the end of the search.
Research published by the National Bureau of Economic Research in 2026 also examined realtor-loan-officer referral networks and found that referred borrowers in its study paid higher rates on average than borrowers with less referral exposure. The researchers estimated an 18.4-basis-point difference, or about $2,585 upfront, while noting that referral networks can reduce the amount of lender searching borrowers do.
How to Avoid Overpaying for Your Mortgage
The good news is that borrowers have several ways to make mortgage shopping more thorough.
1. Compare Multiple Lenders
Getting more than one mortgage quote gives you a better way to evaluate the pricing you’re being offered.
Compare more than just the interest rate. Look at:
- Interest rate
- Annual percentage rate (APR)
- Origination fees
- Discount points
- Lender credits
- Closing costs
- Monthly payment
- Loan program and terms
A lower rate isn’t automatically the better offer if it comes with significantly higher upfront costs.
2. Ask Lenders to Review Their Pricing
Once you have multiple offers, you can ask lenders whether there is room to improve the rate, fees or overall pricing. Lenders compete for borrowers, and having another legitimate offer gives you useful information when comparing the proposals.
The goal isn’t simply to find the lowest advertised rate. It’s to understand the total cost of the mortgage and how each lender’s offer compares for your specific situation.
3. Compare the Same Loan Scenario
Mortgage offers are much easier to compare when the underlying loan is the same. For example, if one lender quotes a 30-year conventional loan with one set of points and another quotes a different loan structure, the rates alone won’t tell you which offer costs less.
Ask each lender to price the same:
- Loan amount
- Property type
- Loan term
- Loan program
- Down payment
- Credit assumptions
- Rate-lock period
This creates a more useful apples-to-apples comparison.
4. Understand the Fees
The interest rate isn’t the only cost associated with a mortgage.Borrowers should review the Loan Estimate and pay attention to lender fees, points, credits and other closing costs. Understanding those numbers can make it easier to determine whether a lower rate actually provides a meaningful financial benefit.
The Philadelphia Fed’s research also found no evidence that more expensive mortgage lenders provided a better borrower experience, although individual experiences can vary.
Does the Lowest Rate Always Mean the Best Mortgage?
Not necessarily. Mortgage pricing involves more than the interest rate. A lender could offer a lower rate while charging additional points or fees to obtain it.
That’s why borrowers should compare the complete loan structure rather than focusing on a single number.
The right comparison depends on factors such as how long you expect to keep the mortgage, whether you plan to refinance, how much cash you have available for closing and which loan features matter to you
What About Your Current Mortgage?
Mortgage shopping doesn’t necessarily end when you close. If you’ve already purchased a home, it can still make sense to periodically review your mortgage, particularly when market conditions change or your financial situation changes.
For some homeowners, refinancing may create an opportunity to lower their rate or monthly payment. However, refinancing also comes with costs, so the potential savings need to be weighed against the expenses of obtaining the new loan.
Homeowners who aren’t considering a refinance can also review other factors affecting their monthly housing costs, such as mortgage insurance, homeowners insurance and property taxes.
The Bottom Line
Recent research highlights how much mortgage pricing can vary and why comparing mortgage rates matters. Its 2025 analysis found that 87% of borrowers paid above the competitive benchmark used in the study, with an estimated average excess cost of $3,343 per year.
That doesn’t mean every borrower can simply find a dramatically lower rate. Your credit, loan type, down payment, property, timing and other factors all influence the offers available to you.Still, getting multiple quotes and comparing the complete cost of each loan can give you a clearer picture of what’s available before you commit.
For homebuyers, working with a mortgage professional can also make it easier to understand the differences between loan programs, pricing and closing costs. Loan Pronto can help borrowers compare their mortgage options and understand how the numbers fit into their overall homebuying goals.
